A few typos, but this had me wallowing in my feels. This is why Celestia is one of my favorite characters, and my favorite ruler out of any series: because she's so damn old, to put it bluntly, and old people make me feel sad. And sad means happy for deep people. <--who got that reference?

Happiness may spring eternal, but life cannot, therefore, neither can happiness. Such is the cycle of the world, and maybe a new race will come to take the place of the long lost Equestrians. Maybe something... bipedal?

i only have one question: what happened to all the other sentient races of Equestria, like Dragons, Griffins, Changelings and Diamond Dogs? they don't seem like the types of creatures that would just stop breeding, nor do any of them seem to be evil enough to annihilate one another. just a thought.

Well as for the griffons, I consider them a very unique type of pony, thus they faded away like the rest. The diamond dogs, without any sort of victims to prey on, were not intelligent to survive on their own, often dissimilating, and fleeing into the wilderness, to expire. The changelings, as far as I'm concerned were wiped out long ago, when Cadence and Shining armor banished Chrysalis, and whatever few may have remained, have long since perished. As for the dragons, they had experienced a decline after many centuries, an ancient race unsuited for the newer times, and thus, were incompatible with the generations that superseded them.
